SASH-FASTENER.

Specification of Letters Patent No. 28,322, dated May 15, 1860.

To all whom it may concern:

Be it known that I, JOSIAH M. WHITNEY, of Astoria, in the county ofQueens and State of New York, have invented a new and ImprovedSash-Fastener; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing, making a part of this specification, in which-Figure 1 represents a transverse vertical section of my invention theline 00, 00, Fig. 1 indicating the plane of section. Fig. 2 is a faceview of ditto.

Similar letters of reference in both views indicate corresponding parts.

To enable those skilled in the art to make and use my invention I willproceed to describe its construction and operation with reference to thedrawings.

A, represents the frame of a window in which the inner sash B, and theouter sash B slide up and down in the usual manner. Such windows caneasily be opened from the outside, as well as from the inside, bypushing down the outer, or by raising the inner sash, and dishonestpersons, in many cases take advantage of this fact to enter a houseclandestinely. For this reason it is desirable to have some simple andreliable device which prevents persons opening the window from theoutside, and various de vices have been proposed for this purpose, butsuch are more or less defective. In order to make such a device answerits purpose, it must be simple and cheap, and at the same time it mustbe strong enough to resist any power which may be applied to either sashin order to open the window, and it must also be so arranged that it isimpossible to. push back the fastener by means of some instrument thatmay be entered between the two meeting bars of the inner and outer sash.Such is my device, which consists of a brace C, hinged to a plate a,that is screwed down firmly to the top of the meeting bar 6, of theinner sash. This brace catches into a notched plate D, that is fastenedin a mortice in the side rail of the outer sash as clearly shown inFig. 1. The notch C, in this plate is deep enough to admit the fullthickness of the brace C, and the brace thus forms a strut, thatprevents the inner sash being raised, or the outer sash being pusheddown. In order to secure this strut in its position I have hinged to theplate a, a dog E, which, when turned up, catches under a nose d, thatprojects from the back of the brace C, and if thus secured the brace cannot be pushed back from the outside by means of a knife or any otherinstrument that may be entered between the meeting bars of the inner andouter sash. This instrument I consider much simpler and quite aseffective as a slide that may be employed to secure the brace or strutC, in its position. Such a slide is not only more difficult to make, butat the same time if it has been in use for a short time, it sticks andits operation becomes troublesome. The dog E, on the other hand can beturned up and down under all circumstances, and at all times with equalfacility, and it secures the brace C, in such a manner that the windowcan not be opened from the outside without breaking some portion of thesame.

My device can be made very cheap, all its parts being cast, and nofitting being required, and by a slight alteration it can be used forfastening doors as Well as windows.

Having thus described my invention I claim and desire to secure byLetters Patent- As an improved article of manufacture a window sashfastener composed of a plate a, hinged nose strut C, and hinged dog E,arranged as shown.
